perfect alignment between
the race and the guides,
making for greater reliability
in the insertion elements,
requiring less maintenance

the delicate procedures for
race/lateral guide alignment
are now a thing of the past.
The distinguishing features
of the Alpha PGA structure
are thus exceptional strength
and rigidity, decisive factors
if one wants to exploit to the
full the huge potential of the
new drive units.
Decisive structural solidity
The Alpha PGA has been
designed to meet superior
standards of versatility and

characteristics are the basis
for an absolute quality at all
weaving conditions.
The special design of the
100% cast-iron side frames
and their great solidity have
done away wi th the need
for further beam supports.

these elements has made it
possible to incorporate the
take-up roller drive gear inside
the frame itself.
A solution that gives the loom
great stability, no vibrations
and great
precision in construct ion

weaving even at high speed
and with heavy work loads.
The two cross bars, made

rom bent sheet metal, and
the overal l structure have
been designed using the
latest kinetic and dynamic
analisys systems: the main
result here is extremely high

almost complete absence of

The size of the sley shaft has
